[ARCHIVED THREAD] - Help with barrel ID

I came across a barrel of unknown make and was wondering who made it. It is a 16" m4 profile marked: AA 5.56 NATO HC

Anyone know what it is and what the letters stand for?

Anvil Arms barrel.

Most likely 1/9 twist.

NATO = North Atlantic Treaty Organisation.

HC (and this is just a guess) = Hard Chromed.
